VICTOR SINCOVITZ, OF PUEBLO, COLORADO'.

AUTOMATIC RAIL FEED.

To all 'whomvt may concern.'

Be it knownthat I, VICTOR SiNoovrrz, a citizen of the United States, residing at the city of Pueblo and county of Pueblo and State of Colorado, have invented certain new and useful Improvements in Automatic Rail Feeds; and I do declare the following .to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it fappertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of thisV specification.

The object of this invention is toprovide efficient automatic means for feeding rails to cutting devices whereby the 'rails are cut into short sections.

Briefly, the invention comprises a series of live rolls by means of which each rail is fed individually to the cutting device. The forward end of the rail is adapted to engage a trip plate to lift the same for the purpose ofsetting a pawl on a ratchet, the weight of the trip plate being sufficient, when disengaged by the rear end of the rail, to rotate the ratchet when said plate drops and thereby rotate a series of rail-feeding sprockets capable of feeding one rail at a time to the live rolls. n i

V,In the drawings: n

Fig. 1 is an end elevation showing the application of the invention;

Fig. 2 is a front elevation as indicated by line 2 2 of Fig. 1;

Fig. 3 is a fragmentary horizontal detail indicated by the line 3 ofFig. 2;

Fig. 4 is an elevation of one of the railfeeding sprockets as indicated by line 4 of Fi. 3

Fig is an enlarged detail indicated by the arrow 5 of Fig. 2, showing a trip plate in plan; and

Fig. 6 is a side elevation of the trip plate as indicated by the line 6 6 of Fig. 5.

A plurality of standards 10 support a plurality of inclined rail-receiving slides 12 upon which the rails to be handled are placed. A small stop 14 is provided adjacent the lower end of each of the slides 12 to limit the sliding motion of said rails, due to gravity. A row of short standards 15 are provided in the front of the device and spaced from the forward standards 10, a plurality of cross bars 16 extending between the front standards 10 and said standards 15. Rail- Specication of Letters Patent. Patented Feb. 28 1922. Application filed March 9, 1921.

Serial No. 450,914.

guiding members 18 are connected with said cross bars 16 and the forward end of the slides 12, the forward portions of said guides 18 being inclined as shown, for the purpose of conducting a rail as it is fed forward onto a plurality of live rolls 2O which are driven by means of aline shaft 22 and beveled gears 24 having a driving connection with the shafts 25 of the rolls 20.

A pluralityV of rail-feedingk sprocketv wheels are ixedly mounted on a longitudinally-extending shaftl 32 journaled in bearlngs 34 carried by said cross bars 16. The sprockets 30 are so arranged that the teeth .thereof will engage under the rail engaging the stops 14 to lift the same therefrom as the sprockets 30 are rotated, so as to support the rail upon the sprockets as indicated. The sprockets are rotated step by step so that a rail is lifted from the slides 12. at each step and a rail is discharged from said sprockets to the live rolls 20 at each step. The rail shown in dotted lines in Fig. 1 is in the position when just discharged from the sprockets 3() onto thev guides 18.

For the purpose of rotating the sprocket wheels 30 to feed the rails, a ratchet 35 is fixedly secured to said shaft 32 at a point in the direction of feed of the rails and beyond their position as fed from the sprockets. The bearings 36 on the ends of arms 38 are journaled on said shaft 32, the forward ends of said arms 38 carrying a heavy trip plate 40 whose face is inclined on an angle as indicated in the various views, the position of the plate being at an angle to the vertical and also at an angle to the horizontal. The lower end of the plate, which is also its forward end, has a roller 42 mounted on a shaft 44 carried in journaling ears 45 of said plate 40. The back or upper side of the plate is provided with an integral re-enforcing'rib 46 which also provides means for connection of the various arms 38. ,If desired, the arms 38 and late 40 may be cast in one heavy piece. rPhe middle one of the arms 38 is divided, as shown in Figs. 5 and 6, and is provided with journals 48 to receive a pivoting pin 5() by means of which a pawl 52 is pivoted on said arm. The free end of the pawl 52 is provided with an engaging tooth 54 adapted to engage the teeth of the ratchet wheel 35 for rotation of the latter.

In operation, the rail is fed by the live rolls 20 in the direction of the arrow in Fig. 5, the end of the rail being forced against the inclined lower face of the plate 40 whereby the continued motion of therail against said face Causes the plate 40 to beVV lifted, the arms 38 swinging on the shaft When the lifting movement j 35 together with the. shaft 32 and the sprocket. wheels 30 so asto feed one rail onto the guides 18 and thence to the live rolls 20- and to lift another rail which engages the stops 14 from the slides l2.' 'j

From the foregoing it will be seen that lf have provided comparatively simple and automatic means for feeding one rail from a pile and onto a series of live rolls as rapidly as a rail is fed forward by said live rolls.

I claim:

l. A rail feed comprising a trip/adapted to be moved by a moving rail,y andv means operable by said trip to feed a rail.

2. A rail feed comprising a tripA adaptedv to be moved byla moving rail, means to move the rail, and means operable by the'trip to feed another rail to Vsaid moving means after passage of the first rail. e'

A rail feed comprising means toy move a rail longitudinally, a. trip adjacent said means adapted to be moved by a moving rail, means for supplying rails, and rail-feeding means operable by said trip to take a rail from said supplying means and to feed a rail to said moving means, 4. A rail feed comprising means tojmo've a rail longitudinally, a weighted trip adjacent said means adaptedto. be Vlifted vby the advancing end of a moving rail, and rail-feeding meansoperable by said trip when it falls after disengagement by said moving rail to feed a rail to said moving means.

A rail feed comprising means to move a rail,longitudinally, a weighted ytrip adfeeding means operable by said trip when it j falls after, disengagement by said moving rail tofeed a rail to said moving means, said rail-feeding means valso being operable' by said trip to take a rail from arail supply.
